Modify a Repeater Control column?

I have a Web App in which a specific form is utilizing an asp: repeater control. This control has 4 columns. I need to modify the 2nd column in order to make it a hyperlink which, when clicked on will need to execute a code- behind function to generate a report. My problem is that I do not know how to configure the 2nd column to make it a link as well as have it it access a code-behind function. Any ideas?
